The Video Server uses a 3.0V CR2032 Lithium battery as the power 

supply for its internal real-time clock (RTC). This battery will, under 

normal conditions, last for a minimum of 5 years. Low battery 

power affects the operation of the RTC, causing it to reset at every 

power-up. A log message will appear when battery replacement is 

required.

The battery should not be replaced unless required!

If the battery does need replacing, observe the following points:

Caution!

• Danger of Explosion if battery is incorrectly replaced

• Replace only with the same or equivalent battery, as 

   recommended by the manufacturer.

• Dispose of used batteries according to the manufacturer's 

instructions.
